According to PMO sources, a message was sent to Mamata that Prime Minister Manmohan Singh was willing to speak to her if she wanted.

The meeting at the Town Hall in Kolkata has been called by Trinamool Congress chief Mamata Banerjee as the 72-hour deadline set by her for the government to go for a roll back on FDI in multi-brand retail and diesel price hike has ended.

It is expected that the Trinamool Congress may decide to pull her ministers out of the UPA and extend issue-based support to the alliance.
